' i, l Y GEORGE- D. Henneman, or comunas, esonera.

To all fr/10m t maje/ concer/n Be it known that I, GEORGE D. Hxn'rs-HORN, a citizen of the United States. residing at Cordele, in the countyof Crisp and State of Georgia, have invented a new and useful SprayingMachine, of which the fol-- lowing is a specification.

This invention relates to a spraying machine designed primarily for usein the treatment of cotton plants and other vegetation whereby poisoncan be distributed over the foliage for the purpose of killing bollweevils and other insects detrimental to the plants.

Another object is to provide a structure of this character whichoperates both to apply a liquid to the foliage and to distribute itthereover through the action of wipers provided for that purpose,thereby to insure distribution of the liquid to all portions of thefoliage.

Another object is to provide wipers which also operate as means foragitating the. plants so as to knock on perforated squares and alsodisturb the insects so that they will emerge from the squares.

A still further object is to provide simple and efficient means whereby.during the forward movement of the machine the fluid to be distributedis placed under compression so that its discharge in the form of a sprayis insured.

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it Vbeing understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings Figure 1 is a plan view of the machine.

Fig. 2 is a side elevation thereof, one of the combined wiping andagitating units being removed.

Fig. 3 is a side elevation of one of the spraying nozzles `and adjacentparts.

Fig. t is an enlarged section through one of the fingers ofa` wipingunit.

Fig. 5 is an elevation of a portion of one of the disks.

: A' l sPRAYING MACHINE. U

Renewed Becember 12, 1924.

Referring' to the figures by characters of reference 1 designates aframe the sides of which converge at the front end as shown at 2 toprovide a tongue 3 to which is connected a standard l having a runner atits lower end. This runner is employed for supporting the forward end ofthe machine. lt is to be understood, however, that any other suitablemeans may be utilized for this purpose. The back end of the frame can beformed of a transversely bowed portion 6 integral with the sides of theframe as shown in Fig. 1.

On the front portion of the frame is mounted a tank 7 in which issupported a pump cylinder 8 having an inlet 9 and an outlet 10, theoutlet opening into a cylinder 11 to the upper end of which areconnected flexible tubes 12 or the like provided at their outer endswith nozzles 13. These nozzles are supported by adjustable bracketswhich are preferably formed of arms 14 and 15 clamped together as shownatv16 and provided with any suitable means such as a split sleeve 17whereby the brackets can be secured adjustably to a transverselyextending rod 18 mounted on and extending laterally from the frontportion of the tank 7. Arranged over and in front of each nozzle is adellecting blade 19 for the purpose of breaking up a jet of liquiddischarged thereagainst, thereby to produce a fanshaped spray. Thisnozzle and deflector can be of any well known construction and dctaileddescription thereof is not deemed necessary.

A standard 20 is mounted on the top of the tank 7 and fulcrumed thereonis a lever 21. Connected to this lever at one side of the standard is alink 22 adapte-d to transmit motion to a piston rod extending from apiston 24 slidable within the cylinder 8. Any suitable arrange-ment ofvalves, not shown, may be provided whereby during the upstroke of thepiston 24 liquid will be sucked from the tank 7 through inlet- 9 int-ocylinder 8 and, during the downstroke of lthe piston, said liquid willbe forced from cylinder 8 through outlet 10, into cylinder 11 and thenceto the flexible hose or tubes 12.

Pivotally connected to one end of the lever 21 so that standard 2Oprojects between it and the rod 23 is a rod 25 slidable within the topof the tank and connected to an agitating disk 26. Thus duringoscillation of, lever 21thc pumppistoii 24 will be actuated and theagitating vdisk 26 will be reciprocated so as to thoroughly stir thecontents of lthe tank 7. The construction of the disk 26 isy immaterialas suitable agitating ineans can be used. It is for this reason that nodetailed illustration or description thereof is given. Y

Extending downwardly from'the sides of the frame f are brackets V27 inwhich is mounted an axle 28 supported by wheels29. A transverse shaftBOis journaled on the frame l and is provided with a disk 3l having awrist pin 32`connect`ed by a rod 38 to one end of lever 21. A sprocket34 is se curedto this shaft and is adapted to receive motion through achain 35 from a sprocket 86 rotating with one of the wheels 29. Thuswhen the machine is moved forward, lever 2l will be actuatedv toagitateand Vexpel the contents of .tank 7. n

Another transverse shaftf?. is journaled on the frainel andv has itsends extending laterally beyond the frame. To this shaft 37. is securedva gear 38 meshingl with. a similai' gear 39 secured to and rotating'withshaft 30. Thus when the machine is moved forward the shaft 37 will berotated.v` y

Mounted on each projecting end of the shafttBT are opposed spacedfdisks40 each ofv which has a hub 41- adjustably secured totlie shaft Vinany-suitable' manner7 as by means of set screws 42. Extending from eachof the disks 40 'are concentric series of combined avgitatinz;v andwiping lingers 43 and 44 the fingers 44 of the inner. series beingpreferably extended substantially horizontally and ltoward/ thecorresponding fingers on theopposed diskV adjacent thereto. The fingers43'of the outer series on the two adjoining disks converge outwardly asshown. These fingers can be of any pre? ferred construction. In the formillustrated each finger includes a coiledspring 45. Isecured at one endto the disk. This'spring projectsv into a tubular member 46 formed of avclosely woven'fabric. Thedisks, when rotated with ythe' shaft' 37 willcause the various fingers' to agitate the plants'and to wipey thereoverany lliquid Athat'may have been sprayed upon the plantsffr'om the noz-jzles 13. It is to be understood that ythefnoz zles 13 are `substantiallyequi-'distant be- CJi CTI

` tween theiplanes1 o-fftlie disks at 'the respective .sidesof themachine an'd'thedisks are kso:l located .Y that? when the machine Vispropelled vover a field `arow of plants 'will bere'ceived .between fthedisks of each pair.

Duringthis :operation a poison liquid will be expelled through thenozzles as before explainedandt'delivered onto the' plants.

The disksfand 'agitating fingers rotate oppositely to the wheels2'9.;`and the fingers serve Y as 'before 'eX/plained'bothf'to' agitate'theplants and' to. wipefthe poisonrrliquidg over them. Thus the insectswithin the rpunctui'ed squares will be disturbed, will emerge7 and feedupon the poisoned foliage. Many of the perforated. squares will beknocked fi'oii'i thel plants so that they can be picked up by anysuitable means provided for that purpose.

I It is to be understood that other types of fingers can be used thanthe ones shown in Fig. 4 without departing from the spirit of.- theinvention as claimed.' i

For the purpose Vof filling the tank 7, al' filling opening maybe formedin the top:V

normally closedy :i

thereof, this opening Ybeing by means of a cap '47.

The machine is provided with .suitably braced handle bars48 attached.'to thefsidesV thereof and provided withl grips 49 so thaty it can bemanipulated.readily. A horse or.

any other means canbe used for drawing. the machine over afield.
